  2. Geometry M05.C-G.2.1.1 - Classify two-dimensional figures in a hierarchy based on properties

  3. Objective • Mathematicians will classify and categorize quadrilaterals into a hierarchy on their interactive notebook pages.

  4. Interactive Notebooks • Cut the shapes out. Do not paste yet! • You will have 8 minutes to cut before we move on to guided notes.

  5. Shape attributes • Follow along with the next few slides to identify attributes of each type of quadrilateral • Write EVERY attribute listed on the page for EVERY quadrilateral on your notebook page

  6. Characteristics of quadrilaterals 4 sides and 4 vertices A B G H D H F Do you see any regular quadrilaterals? How do you know? C E I

  7. Symbols > Or >> means parallel II or I means equal means right angle

  8. Parallelogram • 4 sided shape • 2 pairs of parallel sides • 2 pairs of equal length sides • Opposite angles are equal

  9. Rectangle • 4 sided shape • 4 right angles (90°) • 2 pairs of parallel lines • 2 pairs of equal length sides

  10. Rhombus • 4 sided shape • 4 equal length sides • 2 pairs of parallel sides • Opposite angles are equal • The diagonals meet in the middle at a right angle

  11. Square • 4 sided shape • 4 sides have equal length • 4 right angles (90°) • 2 pairs of parallel sides

  12. Trapezoid • 4 sided shape • 1 pair of parallel sides

  13. Kite • 4 sided shape • Adjacent sides (they meet) are equal in length • The angles are equal where the pairs meet • Diagonals meet at a right angle

  14. Independent Practice/ Small groupsVoice level 0/1 • Complete interactive notebook pages • Sort into a hierarchy (think about attributes and the hierarchies we created in class yesterday) • Two-dimensional figures Math around the room cards • IXL Weekly topics • Color by Number • Small groups with Mrs. Schaffer

  15. Closure • What do you call a 5 sided polygon? • What is the name for a 3 sided polygon? • What is an attribute? • How can we use attributes to classify polygons? • What subcategories can be used to describe the set of quadrilaterals? • Which subcategories would squares fall into?
